Background: Acute kidney injury is a common complication of both civilian and military trauma. The lack of dedicated resources restrict dialysis in the forward setting. We report a case of a combat polytrauma and renal failure, using continuous arteriovenous hemofiltration to clear uremia and remove volume, allowing for ventilator liberation and safe disposition. Materials and methods: The patient presented with traumatic lower extremity injuries and abdominal wounds and developed acute post-traumatic renal failure. Using available supplies, the patient was cannu-lated for continuous arteriovenous hemofiltration. Aggressive fluid and electrolyte management accomplished specific goals of ventilator liberation and clearance of uremia. Results: Over 48 h, blood urea nitrogen was reduced from 101 mg/dL to 63 mg/dL. Creatinine was reduced from 8.2 mg/dL to 4.7 mg/dL. Acute respiratory distress syndrome was improved reducing P:F (PaO2:FiO2) ratio from 142 to 210. The patient was extubated and transferred safely. Conclusions: The ability to perform acute dialysis can be lifesaving. Although resource constrained, we created a dialysis system in the forward environment with a filter and universally available equipment. This represents the first described use of continuous arteriovenous hemofiltration at the NATO Role 3 hospital in Afghanistan. This technique represents another potential tool for deployed trauma teams to improve care.
